Objective: To study the physico-chemical patterns of pre-membrane water purification. Research methods: photocolorimetric, spectrophotometric, high-temperature oxidation on a platinum catalyst. Main results: Physicochemical regularities in the removal of humic acids by dynamic membranes based on aluminum and iron hydroxo compounds have been studied. It is shown that in the pH range 3.5-8.8, the maximum retention capacity of dynamic membranes with respect to humic acids is observed at pH 8.8. For dynamic membranes from iron hydroxide, it reaches 96.1% by TOC, the color of the solutions decreases by 98.7%, and for membranes from aluminum hydroxide - at 95% by TOC and by 96%, respectively, the chromaticity decreases. A microfiltration mechanism has been established in accordance with which this process with a sequential transition from filtration with gradual capping in each porous porridge is in the process of filtration with the formation of a precipitate on the surface of the microfiltration membrane. The expediency of using ceramic microfiltration membranes from clay minerals for wastewater treatment with increased and high turbidity is shown. Area of application: water treatment and water treatment.
